The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/7c55a94f60a068dc771419c771483bbf6f94c552 commit 7c55a94f60a068dc771419c771483bbf6f94c552 Author: wangxianzhu <wangxianzhu@chromium.org> Date: Thu Aug 11 19:39:08 2016 Fix fast/repaint/obscured-background-no-repaint.html When the test ran on release bots, the foreground image was never decoded so its opaqueness was always assumed false, and the animated background was always assumed not obscured. (The original test passed with debug build and CQ bots perhaps because of different timing/scheduling.) Force rasterization (in which deferred image decoding is done) with testRunner.capturePixelAsyncThen().
